When you’re preparing for the end of the world, stock up on Sanyo’s eneloop batteries.

The eneloop batteries first came into the market in 2005, but the latest version got a couple key improvements: They can now hold their charge after five years of storage and can be recharged 1,800 times, a 20 percent increase from older generations. As of September, more than 180 million of Sanyo’s envelop batteries have been sold to 60-plus countries.

After the Japan earthquake in March, Sanyo had worked to create batteries with lower self discharge and higher charge-discharge cycles. The product will debut November 14 exclusively in Japan. The manufacturer has not mentioned release dates for other countries.

These batteries hold 90 percent of power after a year of storage. After five years, they still retain 70 percent of their charge. And for when situations get dire, a solar charger can juice up these batteries during power outages.

envelop pro, AA size with 2400 mAh-capacity

envelop plus, AA size with 1900 mAh-capacity
